Resolves a group of message classes to their forms in a form container and returns an array of form information objects for those forms.

HRESULT ResolveMultipleMessageClasses(
  LPSMESSAGECLASSARRAY pMsgClassArray,
  ULONG ulFlags,
  LPSMAPIFORMINFOARRAY FAR * ppfrminfoarray
);

Parameters

• pMsgClassArray
  [in] A pointer to an array that contains the names of the message classes to resolve. Message class names are always ANSI strings, never Unicode.

• ulFlags
  [in] A bitmask of flags that controls how the message classes are resolved. The following flag can be set:

  • MAPIFORM_EXACTMATCH
    Only message class strings that are an exact match should be resolved.

• ppfrminfoarray
  [out] A pointer to a pointer to an array of form information objects. If a client application passes NULL in the pMsgClassArray parameter, the ppfrminfoarray parameter contains form information objects for all forms in the container.

Return Value

• S_OK
  The call succeeded and has returned the expected value or values.

Remarks

Client applications call the IMAPIFormContainer::ResolveMultipleMessageClasses method to resolve a group of message classes to forms within a form container. The array of form information objects returned in the ppfrminfoarray parameter provides further access to each of the forms' properties.

Notes to Callers

To resolve a group of message classes to forms, pass in an array of message class names to be resolved. To force the resolution to be exact (that is, to prevent resolution to a base class of the message class), the MAPIFORM_EXACTMATCH flag can be passed in the ulFlags parameter.

If a message class cannot be resolved to a form, NULL is returned for that message class in the form information array. Therefore, even if the method returns S_OK, do not assume that all message classes have been successfully resolved. Instead, check the values in the returned array.
